Hi all,
I am new to Jboss. I try to access a postgresql db through a stateless session bean.
However the doesn't get deployed in JBoss. It gives the following error message when I
try to deploy.
I think it has to do something with my datasource, because I managed to deploy an
oridinary HelloWorld session bean.
Bean : DatabaseApiEJB
Section: 22.2
Warning: The Bean Provider must specify the fully-qualified name of the Java class
that implements the enterprise bean's business methods in the <ejb-class> element.
